At first, I would think that IMPLEMENT_DYNCREATE must be in the most derived class (since one purpose of the macro is to allows dynamic creation of the document).
Also all pure virtual functions from CUndo have to be defined in that class (or any intermediate class between CUndo and the concrete class).
You should probably only put CDocument in the second macro parameter.

I have a dialog based application. I have the IDOK button set to be the default button. However, when I press "Enter" nothing happens.
The first tab stop is an edit control, so I want to type something in to the edit control and then simply hit enter and have the default button be pressed.
This is a straight win32 application without using MFC. Is there something I need to do other than set the "default button" parameter for the button?
I have also noticed that I can't tab through the controls, might this be related?
Thanks!

MFC does not support that. You must handle it:
-Open YourProject.rc, find the following line
IDR_MAINFRAME TOOLBAR....<br />
BEGIN<br />
BUTTON ID_FILE_NEW...<br />
BUTTON ID_FILE_SAVE...<br />
add this line<br />
SEPARATOR<br />
SEPARATOR<br />
END
-In OnCreate(), use m_wndToolBar.SetButtonInfo(n,IDC_COMBO,TBBS_SEPARATOR, 100)
-In CMainFrame, add a variable m_combo;
-In OnCreate(), use m_combo.Create(...)

Thanks a LOT Mr.Hung Son. But I'm sorry on my part to not to be clear first.
My toolar is not for a Dialog based.... Sorry! ...
I'm making an IE ToolBar, which doesn't consist of these CMainFrame, and above
said functions.
But what i could do is ... Thanks! .... i will certainly give it a try, as
I got some idea how to proceed.
Thanks Once again for taking some time.

How to initialize a child frame window in full screen mode? 
|
|
|
|
|
Try this (where pChild is the child):
CRect rectSave;
pChild->GetWindowRect(&rectSave);
pChild->SetParent(NULL);
pChild->ModifyStyle(WS_CHILDWINDOW, WS_OVERLAPPED);
pChild->ModifyStyleEx(WS_EX_STATICEDGE,WS_EX_WINDOWEDGE,SWP_FRAMECHANGED);
WINDOWPLACEMENT wp;
memset(&wp,0,sizeof(wp));
wp.length = sizeof(wp);
wp.ptMaxPosition.x = wp.ptMaxPosition.y = 0;
wp.rcNormalPosition = rectSave;
wp.showCmd = SW_MAXIMIZE;
pChild->SetWindowPlacement(&wp);
When you're done being full screen, just reverse the process (restore previous size and styles, make a child again).

When I create a DHTML-based dialog, and I add external resources to the HTML code (images, sounds, etc...), ¿where should I store these resources?, ¿how must be referenced form my html code?  I supose that putting them into the executable resource section is the best choice... but I don´t know hot to load them from HTML. 
Thanks.

I'm sure there's a better way, but i used a bit of javascript to compose the resource URLs:
strBasePath = document.location.toString();
strBasePath = strBasePath.substring(0, strBasePath.length-3);
document.body.background = strBasePath + "background.jpg";

It doesn´t work!
I´m still unable to display these images on my dialog, nor using the original file name "title.gif" or the resource index "106" . . .
I´m confuse. 
Thanks.

How are you naming your resources? Make sure you include the name in quotes, or VS will give it a number instead. (yes, you can use a resource index, but i don't remember how off the top of my head. Use a name 'till you've got the kinks worked out.)

I get an error saying arguments are of wrong type.
yet I've declared the buffer I'm reading from (with Write) as a variant - documentation mentions that. I am just trying to set the value of a field in an access db.
Thank you,

Greetings...
I have a custom control similar to a grid and I am using only Win32 techniques. It has two scrollbars - horizontal and vertical on top and bottom.
When I have more rows to show then the client area I show make my vertical scrollbar visible using ShowWindow function with SW_SHOW flag. I am using the following method to set the size of scroll box of the vertical scroll bar.
#define CUST_DEFHIEGHT 25 // the defaul height of each row in the window.
#define CUST_DEFWIDTH 50 // the default width of wach column in the window.
int nRowNotVis; // how many rows are not visible.
SCROLLINFO scf;
// Get the total client rect of the window.
GetClientRect ( hwnd, &rectWin ); // where hwnd is my custom control.
// Then I calculate how many rows are not being shown.
nRowNotVis = (INT)((row * CUST_DEFHIEGHT) - (rectWin.bottom-(2*CUST_DEFHIEGHT)))/CUST_DEFHIEGHT;
// where row is the total number of rows my Grid has.
// I have left 1 row space in the top and bottom each coz I need them for other purpose.
// Then I use the following code to set the info abdout the scrollbar.
scf.cbSize = sizeof ( SCROLLINFO );
scf.fMask = SIF_RANGE | SIF_POS | SIF_PAGE;
scf.nPage = row-nRowNotVis;
scf.nMin = 0;
scf.nMax = nRowNowVis+1;
scf.nPos = 0;
SendMessage ( hwndVScroll, SBM_SETSCROLLINFO, (WPARAM)FALSE, (LPARAM)&scf );
// Doing this does not change the size of the scroll box in the scroll bar and
// the size remains the same as the scrollbar.
What is going wrong ?
The same thing happens when I use set the value of the Horizontal scrollbar
// now for the horizontal scroll bar.
scf.cbSize = sizeof ( SCROLLINFO );
scf.fMask = SIF_PAGE | SIF_RANGE | SIF_POS;
scf.nPage = col-nCol;
scf.nMin = 0;
scf.nMax = nCol+1;
scf.nPos = 0;
Where nCol is the number of columns not shown in the Window and col is the number of column in the window ?
Please help me ?
I am able to scroll the contents in the window properly but my scrollbox size is not getting effected so I am not able to position it properly also.
Thanks in advance.

After changing internal scrollbar parameters (nMin, nMax, nPage) you should use MoveWindow, SetWindowPos etc. to set correct position and size of scrollbars

1.You don't need to use SendMessage because this's your program and your thread. Only use SetScrollRange, SetScrollPos...
2.I guess that you forgot to call RedrawWindow and UpdateWindow

How can we convert a number represented by DWORD to string or std::string.
Example:
DWORD number=731;
I want to convert "731" to standard string and std::string. Plz tell me how ???
|
|
|
|
|
for conversation any number into string I used to sprintf
|
|
|
|

Maybe its not so good, but i use:
char cBuf[5];
string s(itoa(dwNumber, cBuf, 10));

Hi people,
Does anyone have any suggestions on how to implement the following:
I've made a three page wizard and after the user clicks finish on the third page, I want to pop up a small dialog with nothing but a cancel button and a "Please wait while the data is being saved." message.
My initial plan was to let that dialog do the saving, although that means I'll need to make some detours to access the data that needs to be saved. The problem with that is that I can't seem to find the right windows message handler to start the saving procedure in. Basically, I can't find a WM that fires right after the dialog is shown on screen.
Another approach would be to let the wizard itself handle the saving, but in that case I'd have to make my 'please wait' dialog non-modal. And naturally, I don't want the user tampering with the wizard while it's saving. On top of that, it becomes more complicated to implement the cancel button. I can't see that happening without setting up separate threads. That somehow seems too complicated.
Anyone feel like pointing out the simple path that I'm sure is there somewhere? Thanks a lot...

In your WM_INITDIALOG handler, call ShowWindow() to make the dialog visible.

No, you should use threads for your problem. Because you just need a worker thread, so you can use AfxBeginThread.
Ex:
Declare: static UINT SaveThread(LPVOID lParam)
Implement:
UINT SaveThread(LPVOID lParam)
Calling:
AfxBeginThread(SaveThread,yourParam);

i worked in a company before. many apps shared to use a public database, the db (not SQL one) consisted lots of arrays, which hold pointers to some type of objects.
unfortunately, some apps saved bad pointers (pointed to nothing but not null) to the db.
once other apps accessed to those bad pointers, the apps crashed.
do u know how to access to bad pointers with no crash (i.e. find they are bad then skip them)?
thx

Can you provide more detail on the file structure and details of what the crashes are.
In the good old days of DOS, I used to have to manually fix bad pointers in files with a hex editor.

similar to this, i think:
//the database is called "Object Store"
//did by some one else
MyClass p=new MyClass;
delete p;
ary.Add(p); //ary is an Array
db.Save(); //Save to database
//i do
db.Open(file_name);
int i,iNum=ary.GetSize();
for(i=0;i < iNum;i++)
{
int iSomeValue=ary.GetAt(i)->iSomeValue;
}
note: one of ary.GetAt(i) above gets bad pointer.
thx
